Ok, I did a preupgrade to F14 with:
Code:
Name : preupgrade
Arch : noarch
Version : 1.1.8
Release : 1.fc14
Size : 672 k
Repo : installed
From repo : anaconda-InstallationRepo-201010211814.i386
Summary : Prepares a system for an upgrade

Description : preupgrade prepares your Fedora system for upgrading to a newer

: for the upgrade, and then setting up your system to perform the

And now I have F14 installed.

Simplescan is now upgraded to latest version.

Just say that the preupgrade did fine with no hassles, everything went smooth and nice.
